Definition of physical change:
Physical change is a method in which the substance encounters changes in its physical properties, for example, appearance, shape, color, size, etc. With which there has been no change in its molecular composition.
Definition of chemical change:
Chemical change is characterized as the procedure in which particles or atoms are changed or added to form another new substance. When a matter undergoes chemical changes, the chemical properties of the substance change and it changes with a different chemical composition into a different substance. Bubble formation, energy development, temperature changes, odor changes are some signs of chemical change.
Here are some points of difference between a physical change and a chemical change.

It's a process of temporary change |
It is a process of permanent change. |
|
Energy is not absorbed or developed in the process of physical change. |
During the chemical change reaction, the absorption and development of energy occurs. |

It involves changes in the physical properties of that substance, i.e. color, size, shape, etc. |
It involves changes in substance, chemical properties and composition. |
